58 NEW YORK STATE MUSEUM 



by Bailey Willis (Washington, 191 1) followed in 1912 by its 

 description in professional paper 71 of the U. S. survey: "Index 

 to the Stratigraphy of North America " which gives a summary of 

 everything to date (consult pages 120-27, 183-86 for our area). 

 The State Museum also put forth a revised edition of its Hand- 

 book 19 on " Classification of New York Series," which is the 

 present standard. In 1914 came Prof. W. J. Miller's " Geological 

 History of Nezv York State" (Bulletin 168), in which special 

 reference may be made to pages 41 to 51 and others; and Gushing, 

 Martin and Chadwick reported progress on their respective fields 

 in the Director's Report (Bulletin 173) pages 61-67. The last 

 papers to mention are Chadwick's " Post-Ordovician Deformation 

 in the Saint Lawrence Valley" (Geological Society of Amer.ca 

 Bulletin 26:287—94; 1915) in which the names Heuvelton and 

 Bucks Bridge were first employed and a black and white map of 

 the Ganton quadrangle Paleozoics was given, and the stratigraphic 

 tables in Bulletin 92 of the U. S. National Museum, by Bassler. 

 In addition to these. Professor Gushing's bulletin on the Ogdens- 

 burg and Brier Hill quadrangles will probably be issued before this 

 paper is printed. 



In the above catalog no account has been taken of publications 

 on the surface geology, that being reserved for the time when the 

 Pleistocene formations of our quadrangle shall receive the special 

 description that they merit. Papers purely paleontologic have been 

 omitted for citation in the text. 



Of the works named, the most indispensable to local students 

 or amateurs are probably Bulletins 95, 145 and 168 of the State 

 Museum, which may be secured at small cost from Albany, Logan's 

 economic report in the 22d of the State Geologist (56th of the 

 Museum), the revised edition of Handbook 19 which is free on 

 request, and the U. S. Geological Survey professional paper 71. 

 Emmons's 1842 Report on the Second District and the 1863 

 Geology of Ganada are still useful and may be obtained at old book 

 stores. The last state map (1901) is now sold in atlas form only.
